Connecting
For a single-phase version: see the diagram. Use the control panel with the condenser and the
switch.
Protection
Each deep well pump has built-in, manually resettable overload protection and automatically rever
sible overheating protection.
Check direction of rotation
Check the correct direction of rotation. The right direction is the one that gives the maximum height
with the same amount of water absorbed.
Maintenance
Make sure the pump is disconnected from the power supply or the mains switch is off before it is
serviced.
10 cm pumps do not require routine maintenance.
Regularly check the vibration and power consumption.
Decreasing pressure can result from pump wear. Increased power consumption may result from
abnormally high friction in the pump or in the engine.
CAUTION!
The pump contains rubber parts that are used more quickly with oil.
Troubleshooting
Possible causes and solutions
The pump does not press the water
• The water level has dropped. Wait until the water level is restored.
• No power, manual switch is off. Find the problem and turn the manual switch back on.
• The thermal fuse is released. After the engine cools down, it automatically switches back on.
• Check whether valve is clogged.
• There is sand in the pump. Lift the pump and repair it.
Reduced power and pressure
• There is sand in the pump. Lift the pump and repair it.
• The system was clear. Locate the leak and repair it.
• The pump is worn out. Lift the pump and repair it.
The pump switches too often on and off.
• The float switch is probably switched on (the pump is more powerful than the drainage of the well).
Reduce water consumption.
• Excessive power consumption. Mechanical failure. Lift the pump and repair it.
• The liquid temperature is too high. The built-in thermal fuse is activated.
Repair
DANGER!
Only qualified service personnel can repair the electrical device.
If the pump needs repair, it must be sent to the nearest service facility. Look for the warranty guide
for the address.
